DEVICE FOR MAKING VTINDOWS TIGHT AGAINST THE INGRESS AND EGRESS OF -AIR.

To all whom it may concern:

Be it known that I, HENRY HIGGIN, a citizen of the United States, and a resident of the city of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Devices for Making Windows Tight Against the Ingress and Egress of Air, of which the following is a specification.

The several features of my invention and the various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims.

In the accompanying drawings making a part of this specification and in which similar letters of reference indicate corresponding parts, Figure 1 is an elevation of the inside face of a window to which window my invention has been applied. Fig. 2 is a view partly in section and partly in elevation of the central portion of the window shown in Fig. 1, but drawn on a scale somewhat larger than that of Fig. 1. This section is taken in the plane of the dotted line 2, 2, of Fig. 1. In this view the window cap is removed. Fig. 3 is an elevation of a portion of an upper corner of the lower sash and of a portion of a lower corner of the upper sash, and illustrating a means for conveniently drawing together the upper rail of the lower sash and the lower rail of the upper sash. Fig. at is a view in perspective of the double wedge block, shown in Fig. 3. Fig. 5 is a view in perspective of one of the springs adapted to cooperate with the wedge block when the window is closed in drawing the upper and lower sashes together.

I will now proceed to describe my inven tion in detail.

A, A respectively indicate the upright sides, namely: the jambs of the window frame.

B indicates the bottom cross-piece or sill of the window frame, and 13 indicates the top cross-piece or lintel of this frame.

glass. D indicates the lower rail of this sash and D indicates the upper rail of this sash. D indicates the stile (upright piece) constituting one side of this upper sash, and D the stile constituting the other side of this upper sash. This sash has glass D.

The sashes C and D are arranged so that sash D can pass down behind sash C, and sash O can pass up in front of sash D. The window frame is provided with the usual strips or beads on the jambs, and these beads serve to form the grooves in which the respective sashes move. Thus F indicates the inside bead, G the parting or middle bead, and H the outside bead. In the groove J, between the inside bead F and the parting bead G, the window sash C runs. In the groove K, between the parting bead G and the outer bead H, the sash D runs. Such an arrangement of beads F, G and H and grooves J and K is present at the other or opposite j amb. Thus the construction is, as usual, symmetrical. There is an upper cross parting bead running across the upper or top part of the window frame from one parting bead G on the one side of the window to the other parting bead G at the opposite side of the window.

The outer part of the upper rail C of the lower sash C and the inner part of the lower rail D of the upper sash D are constructed according to a mode now well known and in common use, namely: The rail C between the vertical parting beads G, G, extends outwardly across these parting beads, that is a distance outwardly equal to the width of such bead G. This extended portion S is beveled downward and inward. In like manner, the rail D between the vertical parting beads G, G, extends outwardly across these parting beads a distance equal to the width of such bead G. This extended portion T is beveled downwardand outward. When the lower sash C is down and the upper sash D is fully raised, these beveled portions are quite close together. But between their beveled surfaces there may be a small narrow space, because each sash has necessarily some lateral play, namely: from front to rear. Otherwise each sash would frictionally bind in its respective guideways J and K. In order to cause these rails C and D to come together, when the lower rail is down and the upper rail is elevated, and to be elastically held there, I provide elastic devices of the following preferred form. I provide two wedges ML and MU, one for use with the lower sash and one for use with the upper sash. These wedges are preferably alike. Each wedge has an incline hi and next thereto a hollow or concave portion M These wedges are suitably secured to that parting bead G to which they are adjacent, it being understood that there is a wedge ML and a wedge MU on the parting bead G on the one side of the window and another wedge ML and another wedge MU on the parting bead on the other side of the window. F or convenience and economy of manufacture and for enabling the wedges to be quickly and simultaneously attached to their respective parting beads, I combine a wedge ML and a wedge MU in one block N so that the piece they form is integral, see Fig. 4:. A hole M in the block N receives a screw M, whereby the block is held to its parting bead G. Holes M M in this block N, respectively receive and hold pins which also extend into the parting bead G and serve to prevent the wedge block N from rotating on its screw, and to keep the block N in operative position.

Each end portion of the upper rail of the lower sash, and each end portion of the lower rail of the upper sash is respectively provided with a device for elastically and respectively cooperating with the wedge adjacent to it. A preferred kind of such device is present in Fig. 5. It consists primarily of a spring portion and of a part or parts adapted to be secured to the sash. There is a spring P consisting of a bent wire Q. This wire is bent in a loop, and the two parts of the wire are respectively carried back and each is bent at a right angle. The ends Q}, Q of these right angled end portions are pointed. The loop portion of the wire is curved or bowed at Q}, and the end portion of the loop is curved in a contrary direction. The ends Q Q are inserted into an opening or holes in the sash, substantially as indicated in Figs. 2 and 3. Additional means for securing the loop to the sash consists of a holder R, which consists of a piece R provided with flanges R R his holder R straddles the wires, and is secured to the sash by a screw R passing through the holder R and between the two wires of the loop and thence into the sash as indicated in Figs. 2 and 5.

The operation of this portion of my invention is as follows: When the lower sash C is being lowered so as to shut the window, the outwardly inclined end Q of the spring P meets the adjacent incline M of the wedge and is forced up said incline N and into the concave portion or seat M This operation brings into play the elasticity of the spring P, and the latter draws the upper portion of sash C against the parting beads G, G, and the beveled portion S of the upper rail C toward the beveled portion T of the lower rail D of the upper sash D. In like manner, when the upper sash D is raised to shut the window, the bend Q, of its spring P is forced up on the incline M of the adjacent wedge and is moved on and into the concave portion or seat M The elastic operation of the spring P operates to draw the lower portion of the sash l) against the parting beads and to move the beveled portion T of the lower rail D against the beveled portion S of the upper rail (1 of the sash (1. Thereby the meeting portions of the sashes C and D are tightly brought together, and these sashes bear closely against the parting beads G, G. The lower part of each sash 0, being likewise forced by a spring against the parting beads G, G, renders the junction of the entire sash with the parting beads and with the lower rail D of sash D, a tight one. Likewise the upper port-i011 of the upper sash D, being forced by a similar spring against the cross parting rail and the vertical parting beads G, G, renders the union of this sash with these beads tight, and the lower portion of this sash D being in tight conjunction with the upper end of the lower sash C and with the vertical parting beads G, G, the union of the sashes between themselves and the beads is a tight one and practically no dust nor air nor rain is admitted through the window.

Vhat I claim as new, and of my invention and desire to secure by Letters Patent, is

1. In a window, the combination with the window sash and parting beads, of wedges and springs secured intermediate the sash and parting beads, the wedges to one part and the springs to the other, with the springs arranged to mount on the wedges to draw the sash against the parting beads.

2. In a window, the combination with the window sash and parting beads, of wedges each having an inclined end and concave seat secured to the parting beads, and spring catches each having an inclined end and bowed body secured to the sash, and adapted to ride on one of the wedges and contact with its seat, to draw the sash into contact with the parting beads.

3. In a window, the combination with the window sash and parting beads, of wedges each having an inclined end and concave seat secured to the parting beads, and spring catches secured to the sash, each catch comprising a looped double wire with its looped end bent up and its central portion bowed to ride on one of the wedges and contact with its seat.
